Stainless steel lining technology is a thin-walled stainless steel tube as a carrier for welding molding, the traction winch as the power, the stainless steel liner pipe from the end of the pipeline to be pulled to the other end. After the stainless steel pipe lining is inserted, it is punched, and the gap between the inner liner and the original pipe is grouted and solidified under the condition of holding pressure. A composite tube that is tightly bonded to the original pipe and has a smooth surface. So as to achieve strong pressure, impact resistance, corrosion resistance of the overall repair purposes, to extend the service life of the original pipe for more than fifty years.

Q:304 stainless steel seamless tube weight how to calculate?

304 stainless steel is a common stainless steel material, the density of 7.93 g/cm3, the industry is also called 18/8 stainless steel. High temperature resistance of 800 degrees, with good processability, high toughness characteristics, widely used in industry and furniture decoration industry and food and medical industry.

Q:Stainless steel heating oven tube after treatment is heating blue will not be red?

Because sometimes we do tubular heater, in order to better improve its life, will reduce the heating pipe surface power, but it itself heating speed is slow, take more time to reach the temperature you want.

Q:Stainless steel and stainless steel pipe inside and outside polishing off, what is the difference?

The main difference between these materials is that the chemical composition is different. The corrosion resistance of 316L is stronger than that of 304 and 304L, and that of L indicates lower carbon content and stronger flexibility. Choose the key depends on the things inside, corrosion is not big, how to use the environment, there are high pressure requirements are not high.

1 argon arc welding machine! If the person who has not been married, as little as possible, that thing has radiation, long time use of physiology is influential. You know what you do.2, regardless of the front and back can be, as long as it looks beautiful and practical.3, welding technology is good, it will not be ugly after welding.4, only the use of technology to make up for the lack of machinery, and then cattle B hardware, there is no good software is not good.5, welding rod, protective mask and so on.

Q:What's the difference between the stainless steel pipe welded pipe and seamless pipe?

Concentricity: seamless tube manufacturing process is the temperature of 2200 degrees F in stainless steel billet stamping a hole, at this high temperature, tool steel by stamping and drawing become soft and spiral form from the hole. Thus, the wall thickness of the pipeline is uneven and the eccentricity is high. Thus ASTM allows seamless pipe wall thickness ratio of the wall thickness difference of seamed tube. Through the seamed tube cold rolling plate precision (per roll width is 4-5 feet) made. These cold rolled plates usually have a maximum wall thickness of 0.002 inches. The steel plate is cut into a width of PI D, in which D is the outer diameter of the pipe. Tube wall thickness tolerance is very small, and the entire circumference of the wall thickness is very uniform.

Q:What's the difference between stainless steel 302 or 304?

Type 302 - 304 with corrosion resistance, due to the relatively high carbon intensity. Model 304 - general model: 18/8 stainless steel. GB is 0Cr18Ni9. 302 and 304 stainless steel is widely used in curtain walls, side walls, roofs and other building applications. These two, I think, are basically different. The quality and texture are almost the same.

Q:Disadvantages of stainless steel tubes

Stainless steel pipe is a kind of more durable pipeline material. But its price is higher, and the construction process requirements are relatively high, but its material strength is hard, the field processing is very difficult. Therefore, in the decoration project, the probability of choice is low.

Q:What are the weld sleeves for stainless steel pipes?

Quota refers to the quantity standard of manpower, material resources, financial resources and time consumed by qualified units under certain technical and organizational conditions. In the labor organization reasonable and rational use of materials and machinery under the condition of a predetermined number of resources consumed by the completed units qualified product standards, the level of social productive forces, it reflects the level of a certain period of time. For each construction project, the amount of labor is calculated, including basic labor and other labor. Plus the materials for this project, including basic materials and other materials. The unit price is based on the labor value of the different types of work at that time. The value of the material is the budgeted price based on the previous market price.

Q:How can I clean the stainless steel tube?

1, cleaning stainless steel gently method is simply to use hot water and clean soft cloth to wipe the surface, and then use dry metal with other soft cloth, to prevent water stains thoroughly.2, if ordinary water leaves some dirt or grease, you can add a mild detergent water.
